SIP Trunking vs ISDN: Which Should You Choose?

SIP Trunking FAQs

What is SIP trunking?

SIP trunking refers to a virtual telephone line which connects a business telecoms system to the public phone network. Compared to an ISDN connection, SIP trunk is established via a data network. SIP trunk is often used independently, as an alternative to ISDN, although it’s not unusual for the two systems to be combined to offer a hybrid solution.

How many SIP trunks do I need?

It is easy to calculate how many SIP trunks do I need. Each trunk has capacity for approximately 20 channels. Therefore, if, for example, your contact center needs to be making up to 100 calls simultaneously, you will need five trunks in total.

What is a SIP trunk provider?

A SIP trunk provider is a communications service provider such as net2phone which uses the protocol to provision VoIP connectivity between an on-premises phone system and the public switched telephone network.

When should businesses switch to SIP?

If you are thinking of moving to the cloud to enjoy all of the benefits of a hosted solution, but already possess an on premises PBX system, then a move to SIP trunking should be an easy transition for you.

If you currently use ISDN2 or ISDN30 circuits, and have a leased-line or dedicated SDSL for your internet connections (as opposed to contended ADSL or WiFi), then SIP trunking should be a good fit for your organization.

What equipment will I need?

If you’re using a legacy phone system (and these days, that equates to a couple of years old, or more), you’ll likely need a SIP-ISDN Gateway, which translates the flow of data between the ISDN interface of your existing phone system and your new SIP trunks.

Rather than trusting to the bandwidth of the public internet, it’s a good idea to beef up your existing data connection to allow for the increased demand that will be put on it by voice data.

Will it cost me a bundle?

It certainly shouldn’t. You may need to shell out for a SIP-ISDN Gateway, and you’ll make an upfront payment to your SIP trunk provider to establish a connection. Beyond this, the call and operational charges should actually save you money.
